Linux has in\n> addition device trees M2 and M1 and M2 Pro/Max/Ultra devices which were\n> never added in u-boot.\n> The most common use case for u-boot on Apple silicon devices does not\n> use DTBs from u-boot but passes runtime modified device trees from an\n> earlier boot loader (m1n1).\n> This change regresses support for the SPI on M1 and M1 Pro/Max notebooks\n> as SPI keyboard support is not in upstream Linux. This regression is in\n> my opinion acceptable due to the limited use of u-boot's DTBs for these\n> targets.\n> \n> Signed-off-by: Janne Grunau \n> ---\n> Changes in v2:\n> - Add CONFIG_OF_UPSTREAM_BUILD_VENDOR=y and\n> CONFIG_OF_UPSTREAM_VENDOR=\"apple\" to build all apple DTBs\n\nOoh, that's even better.\n\n> - rebased onto v2026.07-rc1 for Linux v7.0 based DTs in dts/upstream\n> - Link to v1: https://patch.msgid.link/20260430-apple-dt-upstream-v1-0-dda66c16e0da@jannau.net\n\nStill:\n\nAcked-by: Mark Kettenis \n\nfor the series.\n\n> ---\n> Janne Grunau (3):\n> doc: board: apple: Mention M2 and M2 Pro/Max/Ultra SoCs\n> doc: device-tree-bindings: Remove apple,pinctrl.yaml\n> arm: dts: Switch Apple silicon devices to dts/upstream\n> \n> arch/arm/Kconfig | 1 +\n> arch/arm/dts/Makefile | 7 -\n> arch/arm/dts/t8103-j274-u-boot.dtsi | 1 -\n> arch/arm/dts/t8103-j274.dts | 129 ---\n> arch/arm/dts/t8103-j293-u-boot.dtsi | 1 -\n> arch/arm/dts/t8103-j293.dts | 116 --\n> arch/arm/dts/t8103-j313-u-boot.dtsi | 1 -\n> arch/arm/dts/t8103-j313.dts | 111 --\n> arch/arm/dts/t8103-j456-u-boot.dtsi | 1 -\n> arch/arm/dts/t8103-j456.dts | 117 --\n> arch/arm/dts/t8103-j457-u-boot.dtsi | 1 -\n> arch/arm/dts/t8103-j457.dts | 105 --\n> arch/arm/dts/t8103-jxxx.dtsi | 143 ---\n> arch/arm/dts/t8103-pmgr.dtsi | 1138 --------------------\n> arch/arm/dts/t8103-u-boot.dtsi | 25 -\n> arch/arm/dts/t8103.dtsi | 696 ------------\n> configs/apple_m1_defconfig | 4 +-\n> doc/board/apple/m1.rst | 15 +-\n> .../pinctrl/apple,pinctrl.yaml | 106 --\n> 19 files changed, 13 insertions(+), 2705 deletions(-)\n> ---\n> base-commit: 4433253ecf2041f9362a763bb6cb79960921ac7e\n> change-id: 20260109-apple-dt-upstream-6daf03510fec\n> \n> Best regards,\n> -- \n> Janne Grunau \n> \n>","headers":{"Return-Path":"","X-Original-To":"incoming@patchwork.ozlabs.org","Delivered-To":"patchwork-incoming@legolas.ozlabs.org","Authentication-Results":["legolas.ozlabs.org;\n\tdkim=pass (2048-bit key;\n secure) header.d=xs4all.nl header.i=@xs4all.nl header.a=rsa-sha256\n header.s=xs4all01 header.b=SK3k7L29;\n\tdkim-atps=neutral","legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=lists.denx.de\n (client-ip=2a01:238:438b:c500:173d:9f52:ddab:ee01;
